Sometimes they are spelled Hardy and sometimes they are spelled Hardie. Either way they are some of the most important pieces of equipment any blacksmith can have. Here are Hardy tools available on amazon and on ebay. I also have real time ebay listings.

Note about Hardy tools if you are new to blacksmithing. They are always referred to with a measurement. Typically it is 1", sometimes 7/8", sometimes 3/4", or sometimes 1 1/4". These measurements are important. They denote the size of the tang on the hardy tool. And that is the size they fit in the hardy hole in the anvil. So, you have to know what size your anvil hardy hole size is before buying hardy tools! This next image shows the square hardy hole in an anvil. Jujst to the left of it is another hole, a round one. That is the pritchel hole. Measure that square hole!
